Indicator Lights - Grundfos UPS-Serie 200 Montageanleitung

2.2 Connection of external 24 VDC supply voltage
As the LON module is electrically connected via the basic module, it is not
necessary to connect an external 24 VDC supply voltage.
If an 24 VDC supply voltage is connected, the contact to the LON module
can be maintained even if the basic module fails and the supply voltage to
the LON module thereby disappears.
An external 24 VDC supply voltage must be electrically separated from the
mains supply by double insulation.
3. Connection to network
To connect the LON module to the network, activate the Service PIN button.
When the button is activated, the LON module transmits a unique 48 bit
ID-code (Neuron ID), which is registered by the network.
This unique code can also be found on the label situated on the side of the
LON module. The bar code is in Code 128 format.
An additional label with the same unique code is supplied with the LON mod-
ule. This label can be attached to the building installation plan.

4. Indicator lights

The LON module incorporates a green, a yellow and a red indicator light
which are visible through the window in the terminal box cover.
The function of the green and red indicator lights is shown in the table below:

plied with the LON module.
